| 摘 要： | 对8个有代表性的亚麻基因型根系还原量与地上部分主要农艺性状进行研究,结果表明：亚麻还原量以现蕾期至开花期最高,以后逐渐递减.其中上段根系的还原量占总还原量的73.31%-76.86%,中段根系占16.2%-18.17%,下段根系占A.95%-9.26%.亚麻根系还原量与单株果数、单株粒数、单株粒重、单株花朵数呈显著或极显著正相关,与结实率呈负相关.

| Abstract: | The research on the correlation analysis between the deoxidizing amount of root system of eight flax varieties and the main agricultural properties on ground showed that the deoxidizing amounts of flax reached the peak in fruiting and flowering stages, and then reduced. In whole root system, the deoxidizing amounts of the upper, middle and lower section accounts for 73.31% - 76.86%, 16.2% - 18.17% and 6.95% - 9.26% respectively. The deoxidizing amount of flax is correlated positively with fruit number per plant, grain number per plant grain weights and flower numbers significant or extremely significant, and negatively with fruiting probability. |
